Magnesium oxide stabilized zirconia foamed ceramic filter screen and preparation method thereof
The invention relates to the technical field of zirconium oxide foamed ceramics, in particular to a magnesium oxide stabilized zirconium oxide foamed ceramic filter screen and a preparation method thereof. The magnesium oxide stabilized zirconia foamed ceramic prepared from the magnesium oxide stabilized zirconia ceramic slurry has the advantages of reduced shrinkage rate, lower skeleton surface roughness, high strength, uniform microstructure and strong high-temperature deformation resistance, and the green body of the foamed ceramic has the advantages of high sizing speed and low possibility of slurry falling, thereby saving the production time. The volume density of the magnesium oxide stabilized foamed ceramic filter screen prepared by the preparation method of the magnesium oxide stabilized foamed ceramic filter screen can reach 0.75-0.9 g/cm < 3 >, the porosity reaches 80% or more, the bending strength reaches 4.95 MPa or more, the sintering shrinkage rate is 7-8%, and the magnesium oxide stabilized foamed ceramic filter screen meets the requirements of the market on high-standard zirconium oxide foamed ceramic filter screens.
本发明涉及氧化锆泡沫陶瓷技术领域，尤其涉及一种氧化镁稳定氧化锆泡沫陶瓷过滤网及其制备方法；采用氧化镁稳定氧化锆陶瓷浆料制备的氧化镁稳定氧化锆泡沫陶瓷的收缩率降低，骨架表面粗糙度较低，而强度高，微观结构均匀，抗高温变形性能强，而且泡沫陶瓷生坯上浆速度快，不易掉浆，节约了生产时间。氧化镁稳定泡沫陶瓷过滤网制备方法制备得到的氧化镁稳定泡沫陶瓷过滤网体积密度可达到0.75～0.9g/cm3，同时孔隙率达到80％及以上，抗弯强度达到4.95MPa及以上，烧结收缩率在7％‑8％之间，符合市场对高标准氧化锆泡沫陶瓷过滤网的要求。
